Title: Low profile ice maker
Inventor: PANNHOFF DONALD G
IPC: F25C1/12
Filed: 1999-05-14
Abstract: The present invention comprises a low height ice maker designed primarily for use in under counter applications. An ice retaining bin includes a top end opening covered in part by a top panel and the remaining part by an ice access door. The bin is secured to a base, the base retaining certain components of a refrigeration system including; a condenser, a compressor, an expansion valve and a hot gas defrost valve. The base also retains a water dump valve, the electronic control for the ice maker and the condenser fan. When the bin is secured to the base, front and rear access areas are defined which areas can be opened by removing releasably securable panels. The control electronics, the condenser fan and high and low side service valves are positioned adjacent the front access. The expansion valve, hot gas defrost valve and the dump valve are positioned adjacent the rear access. An ice cube forming evaporator assembly is secured to an interior surface of the bin. The assembly includes a frame, and secured thereto; an ice forming evaporator, a water distribution tube, a water tray, a re-circulating water pump, a float operated water valve, and an ice drop detector. The water distribution tube, the water pump, the float valve and the ice detector are secured to the assembly frame with hand operable quick releasing means, such as wing nuts and the like. The ice maker herein provides for ease of serviceability whereby, after removal of the ice maker from underneath a counter, the access panels can be removed revealing the commonly serviceable components. The present invention also includes a control having programmed routines for helping to differentiate between transient failures to make ice that are not the result of mechanical failure of any of the components of the ice maker and those that are the result of an ice maker component failure.

Inventor: MCCANN JAMES D
IPC: B41J2/185
Filed: 1999-12-10
Abstract: A single fluid system simultaneously and independently controls multiple print heads of a continuous ink jet printer. An ink reservoir supplies ink to the multiple print heads and a common vacuum system withdraws ink from the multiple print heads back to the ink reservoir. The system controls the concentration of ink to the multiple print heads and separately supplies ink to the multiple print heads. Multiple print heads are supported independently by this single fluid controller, allowing each print head to operate independently, as if it were controlled by its own fluid system. Hence, each one of the multiple print heads has the capability of cleaning, shutting down, and printing without any interference from the other, while sharing similar components.
